Shark Community Structure In Winyah Bay, Sc, Keenen Fryman
Shark Community Structure In Winyah Bay, Sc, Keenen Fryman
Honors Theses
Assessments of local shark stocks are vital to understand population trends and their causes. Local data are incomplete despite many studies over many years. The first published study listed all of the shark species found off the coast of SC (Bearden 1965). Following Bearden's work, Schwartz (2003) used a 30 year data set to describe the elasmobranchs found in NC and SC. In 2004, a survey of coastal habitats in southeast NC helped to identify the nursery habitat for C. acronotus, C. brevipinna, C. limbatus, C. obscurus, C. plumbeus, M. canis, R. terraenovae, S. tiburo, and S. lewini (Thorpe et …
How Does Climate Change Affect Coral Reefs?, Rachel Goff
How Does Climate Change Affect Coral Reefs?, Rachel Goff
Honors Theses
Climate change is a very real phenomenon that currently affects many of the ecosystems on Earth. Climate change occurs on a global scale and can be very detrimental to different environments. This occurrence can cause ocean warming, sea level rise, ocean acidification, and increased storm intensity. According to the EPA, the ocean's temperature has increased 1.4°F over the past century, and sea levels have risen 3.2 millimeters through the past 20 years. These changes to the oceans can greatly affect many of the ecosystems that reside in them. One of the main ecosystems that are being affected by climate change …

An Analysis Of Peer-To-Peer Distributed Hash Algorithms In Improving Fault Tolerance In The Hadoop Running Environment, Benjamin R. Knaus
An Analysis Of Peer-To-Peer Distributed Hash Algorithms In Improving Fault Tolerance In The Hadoop Running Environment, Benjamin R. Knaus
Honors Theses
Cloud computing is a “new frontier” in the world of computing. One of the cloud architectures widely used is the Hadoop running environment. Hadoop consists of many parts—including MapReduce, TaskTrackers, and JobTrackers. Right now, there is no fault-tolerance for JobTrackers in Hadoop. This paper analyzes four different distributed hash algorithms (Pastry, Tapestry, CAN, and Chord) that could be implemented inside Hadoop to improve JobTracker fault-tolerance. We recommend Chord as the best suited for integration and improvement of Hadoop.
Application Of Linear Sequences To Cryptography, Amanda C. Yeates
Application Of Linear Sequences To Cryptography, Amanda C. Yeates
Honors Theses
Cryptography is the study of a centuries–old technique of secretly transferring information between parties. Linear recurrences were the chosen method of encryption and decryption in the thesis. The Fibonacci sequence, with its Zeckendorf representation, allows for the flexibility of encoding any number desired based on a particular encoding technique used in the film Sherlock Holmes: A Game of Shadows. The main goal is to find other linear recurrences that possess characteristics similar to the Fibonacci sequence to use as suitable substitutes for encoding. Different sequences were analyzed based on a number of criteria. In order for a sequence to be …
Design And Construction Of An Optical Tweezers, Pavel Aprelev
Design And Construction Of An Optical Tweezers, Pavel Aprelev
Honors Theses
We constructed an optical tweezers apparatus, used it to trap transparent micron-sized particles, and moved those particles within a sample by moving the sample relative to the focal point of the trapping beam. The optical trap was based on the fact that focused coherent light creates forces on dielectric objects that point towards the focal point. The magnitude and the span of the force are dependent on the size of the focal point of the beam - generally around 1µm - and the intensity of light. We used an 808 nm 200 mW laser and a piezoelectric stage to trap …
Market Mechanisms And Price Volatility In New York Electricity Markets, Kimberly Blecich
Market Mechanisms And Price Volatility In New York Electricity Markets, Kimberly Blecich
Honors Theses
The past two decades have born witness to a cascade of new legislation and market design measures to restructure the United States’ electric power industry from price-setting regulatory agencies to competitive markets. Deregulation was intended to increase competition and improve market efficiency while preserving the reliability of the transmission system. Results have varied in success, and deregulation has invariably led to an increase in both the overall price level of electricity and volatility of those prices. Investigating these deregulation consequences is crucial for market operations and retrospective analyses of deployed mechanism outcomes. The objective of this study is to extend …
Hydraulic Fracturing Wastewater: Treatment Methods For Flowback And Produced And Water, Claire Cummins
Hydraulic Fracturing Wastewater: Treatment Methods For Flowback And Produced And Water, Claire Cummins
Honors Theses
In order to prevent groundwater contamination that could potentially put millions of human’s health at risk, as well as billions of the federal government’s money on solving the problem, hydraulic fracturing needs to be heavily regulated. This will ensure that hydrofracking is being done in an environmentally responsible way by every natural gas drilling company and not just those who are willing to pay extra for systems and treatment methods that are more expensive but also more effective. The technology for treating hydrofracking wastewater has not been fully developed and would be used a lot more widely throughout the industry …
A Cross-Country Analysis Of Energy Efficient Development, Nicholas Fleagle
A Cross-Country Analysis Of Energy Efficient Development, Nicholas Fleagle
Honors Theses
Maximizing energy efficiency, producing as much as possible with as little energy as possible, is something every country should be working toward. This study measures the efficiency of specific countries by examining the interrelationships that exist among each country’s energy consumption and such measures of development as health, education, income, access to essentials and CO2 emissions. It then analyses why certain countries are more efficient than others and how these inefficient countries can improve. Data Envelopment Analysis (DEA) is used to generate a cross country comparison of energy efficiency scores over multiple dimensions of development. Pairs of inefficient countries and …
Cellular Automata And Music: A New Representation, Richard French
Cellular Automata And Music: A New Representation, Richard French
Honors Theses
For millenia, we’ve thought of musical composition as a purely human activity. However, we once also thought of an activity like chess to be purely human, but Deep Blue was able to defeat Kasparov in 1995 all the same. Could there perhaps be some tool or algorithm for musical composition that can replicate to some extent what human beings can do with music? This project explores this idea through the use of a tool called a cellular automaton. A cellular automaton is a grid space with a finite number of states for each of the ”cells” or ”squares” where a …
Proton Induced X-Ray Emission Spectrometry Of Atmospheric Aerosols At Piseco Lake, Adam Margulies
Proton Induced X-Ray Emission Spectrometry Of Atmospheric Aerosols At Piseco Lake, Adam Margulies
Honors Theses
Chemical studies of lakes and aerosols in the Adirondack region of New York State have found evidence of environmental pollution resulting in acid rain. We obtained air samples for July and September 2012 from Piseco Lake and analyzed particulate depositions with Proton Induced X-ray Emission (PIXE) spectrometry. We detected an array of light elements, including sulfur particulates in the 0.25 - 8 μm range, possibly stemming from coal combustion in the Appalachians and Mid-West of the United States. We also found systematic errors with the accelerator charge integration system due to beam spreading after the beam passes through the target. …
Elections With Three Candidates Four Candidates And Beyond: Counting Ties In The Borda Count With Permutahedra And Ehrhart Quasi-Polynomials, Adam Margulies
Elections With Three Candidates Four Candidates And Beyond: Counting Ties In The Borda Count With Permutahedra And Ehrhart Quasi-Polynomials, Adam Margulies
Honors Theses
In voting theory, the Borda count’s tendency to produce a tie in an election varies as a function of n, the number of voters, and m, the number of candidates. To better understand this tendency, we embed all possible rankings of candidates in a hyperplane sitting in m-dimensional space, to form an (m - 1)-dimensional polytope: the m-permutahedron. The number of possible ties may then be determined computationally using a special class of polynomials with modular coefficients. However, due to the growing complexity of the system, this method has not yet been extended past the case of m = 3. …
Unconscious Automatons On Facebook, Adam Pere
Unconscious Automatons On Facebook, Adam Pere
Honors Theses
The Internet is a relatively new phenomenon that has completely morphed the modern world. Living on a college campus, I almost never find myself in a room without access to the Internet and social media. I, along with many others in my generation, spend hours per month mindlessly surfing the Internet and Facebook. With my project, I want to start a conversation on the topic of how the Internet has shaped our society and whether these changes are positive or negative. To do so, I have built an installation of three robots and a monitor. Each robot (see Figure 1) …
Bird Mortality In The Human Built Environment, Stacie Schwartz
Bird Mortality In The Human Built Environment, Stacie Schwartz
Honors Theses
Human development is having a detrimental effect on bird populations around the world. One hundred million to one billion birds are killed every year from colliding with human-built structures. I explored factors influencing the inability of birds to avoid man-made structures. If we can better understand these reasons, we can find solutions to this problem. After a known bird avoidance method, fritted glass, was installed in the Wold building, I investigated whether this glass actually deters birds from striking windows. Strikes on windows were noted daily through observation of specific windows on campus. Results show that vegetation outside of windows …
The Effect Of Canopy Organization On The Photosynthesis Of Sphagnum, Brian Solinsky
The Effect Of Canopy Organization On The Photosynthesis Of Sphagnum, Brian Solinsky
Honors Theses
With climate change becoming a greater problem the ability of plants to photosynthesize and sequester carbon becomes more important for us to understand. Sphagnum moss stores more than a third of the world’s soil carbon. Much is understood about the physiology of Sphagnum, but what is generally not understood is the effect of variation in canopy organization in Sphagnum: why are they both rough and smooth? This study examined whether different canopy structures influenced how the canopy uses different angles of light for photosynthesis. The first step was modeling photosynthesis in two simulated structures (rough and smooth) as the angle …
An Analysis Of Horizontal Gas Drilling And Its Impact On Spot Market Pricing: A Focus On The Marcellus Shale Production Potential, Samuel O'Connell
An Analysis Of Horizontal Gas Drilling And Its Impact On Spot Market Pricing: A Focus On The Marcellus Shale Production Potential, Samuel O'Connell
Honors Theses
This paper attempts to quantify how the rapid increase in shale gas production in the past fifteen years has impacted regional natural gas spot prices. This method of natural gas extraction-pumping water mixed with sand and clay first vertically and then horizontally, with clay and sand particulates holding fractures open to allow the flow of natural gas-has a shorter well lifespan and faster decline rate than conventional wells. Through analyzing the degree of market integration between shale gas production and spot prices, we can quantify what impact different shale plays have had on the regional pricing of natural gas. With …
Impact Of The Keystone Xl Pipeline On North American Crude Oil Prices, Shawn Ian Stuart
Impact Of The Keystone Xl Pipeline On North American Crude Oil Prices, Shawn Ian Stuart
Honors Theses
This paper determines the economic impact of the TransCanada Keystone XL pipeline project. As the Keystone XL pipeline is extremely controversial it is beneficial to determine the impact on North American crude oil prices. Determining the economic impact the Keystone XL pipeline will have on crude oil prices will be a large detriment of whether the pipeline is economically beneficial. By using spot crude prices from different regions around North America and adding capacity of crude oil transmission from western Canada to southeast United States this paper determines the changes in regional spot crude oil prices. As the economic conditions …
An Algebraic Approach To Number Theory Using Unique Factorization, Mark Sullivan
An Algebraic Approach To Number Theory Using Unique Factorization, Mark Sullivan
Honors Theses
Though it may seem non-intuitive, abstract algebra is often useful in the study of number theory. In this thesis, we explore some uses of abstract algebra to prove number theoretic statements. We begin by examining the structure of unique factorization domains in general. Then we introduce number fields and their rings of algebraic integers, whose structures have characteristics that are analogous to some of those of the rational numbers and the rational integers. Next we discuss quadratic fields, a special case of number fields that have important applications to number theoretic problems. We will use the structures that we introduce …
An Analysis Of Polynomials That Commute Under Composition, Samuel J. Williams
An Analysis Of Polynomials That Commute Under Composition, Samuel J. Williams
Honors Theses
It is well known that polynomials commute under addition and multiplication. It turns out that certain polynomials also commute under composition. In this paper, we examine polynomials with coefficients in the field of complex numbers that commute under composition (also referred to as “commuting polynomials”). We begin this examination by defining what it means for polynomials to commute under composition. We then introduce sequences of commuting polynomials and observe how the polynomials in these sequences (later defined as chains) along with other commuting polynomials relate to a concept called similarity. These observations allow us to better understand the qualities and …
Interactions Of Zn2+ On Insulin Oligomer Formation, Stability, And Fragmentation: Analysis Using Esi-Im-Ms, Tiffany Culver
Interactions Of Zn2+ On Insulin Oligomer Formation, Stability, And Fragmentation: Analysis Using Esi-Im-Ms, Tiffany Culver
Honors Theses
Insulin is a hormone protein essential to the regulation of blood sugar levels. Although it is active as a hormone in the monomer (single insulin unit) form, it is stored in the pancreas as a hexamer – a coordination of six insulin units and zinc ions. This research analyzes the effects of zinc ions on the formation, stability, and fragmentation of the hexamer and other oligomer species in varying solution and instrument conditions, including the ability of the higher oligomers to transfer from crystallization to solution to a gas phase for analysis using electrospray ionization ion mobility mass spectrometry (ESI-IM-MS). …
Abuse Of Spice, Bath Salts, And Steroids, Rebecca Coburn
Abuse Of Spice, Bath Salts, And Steroids, Rebecca Coburn
Honors Theses
The abuse of three different drugs and whether or not they should continue to be banned in the United States is looked at. These three drugs are spice, bath salts, and steroids. In conclusion, spice and bath salts should continue to be banned in the United States due to the little knowledge known on the drugs and how they affect the body. Steroids on the other hand should only be banned in the use of sports, due to the unfair advantage that it gives users. For individuals not in sports, steroids should be legal since it is their choice to …
Interpretation Of Biological Activity Using An Acoustic Backscatter Sensor (Abs), Courtney Elliton
Interpretation Of Biological Activity Using An Acoustic Backscatter Sensor (Abs), Courtney Elliton
Honors Theses
Acoustics aid in the description of complex processes, such as the suspension of sand particles exposed to local hydrodynamic forces above a rippled bed (Cacchione, et al., 2008). Acoustic data can be applied to several aspects of the marine environment such as marine chemistry, biology, geology, and ecology. The acoustic data collected in this study was part of a larger, grant-funded project that focused on sediment transport and settlement preference on two offshore hardbottoms following beach renourishment along the heavily developed coast in northeastern South Carolina. Acoustic data collection was used in the larger project to describe changes in sediment …
Integrating Science & Policy, Abigail A. Carson
Integrating Science & Policy, Abigail A. Carson
Honors Theses
Millions already owe their lives to scientists for their research and implementation of early warning devices such as a tornado warning. These warning systems are the beginning for what is to come if science continues to receive backing. Think of what could be accomplished in the next century if science and policy were to unite in the interest of protecting humans and the environment. It is imperative that environmental policies be based on sound science; to achieve this, political and scientific sectors must be integrated to produce effective and practical policies.

Localized Meshless Methods With Radial Basis Functions For Eigenvalue Problems, Amy M. Kern
Localized Meshless Methods With Radial Basis Functions For Eigenvalue Problems, Amy M. Kern
Honors Theses
Two localized meshless methods with radial basis functions are considered for solving eigenvalue problems on two different domains, i.e., a L-shaped domain and an irregular domain. The irregular domain used in this study comes from an application of the eigenvalue problem as it plays a role in the reconstruction of velocity vector fields. This study finds that both localized Kansa’s method and the Localized Method of Approximate Particular Solutions provide a good numerical approximation to the solution of the eigenvalue problem. Through numerical experiments, a good value for the shape parameter can be determined for each domain for each method …

High Performance Network Communication Between High Frequency Application Servers And Android Tablets, Brandon L. Wolfe
High Performance Network Communication Between High Frequency Application Servers And Android Tablets, Brandon L. Wolfe
Honors Theses
This thesis will develop methods for comparing NORM protocol in unicast mode to TCP by simulating high performance network communication between Android tablets and high frequency application servers. Since mobile network conditions vary based on service provider or tower distance, we will test over a wide range of network conditions such as high delay or high loss, as well as high chances of packet corruption or duplication. We want to maximize speed of data delivery without sacrificing the integrity of the data. The methods used will be generically applicable to multiple operating system platforms and will be cross-platform compatible.
